Deadline is reporting that Milo Ventimiglia has officially joined "L.A. Noir" to play Ned Stax, a former marine turned lawyer who is in the pocket of the mob. "L.A. Noir" takes place during the 1940s and '50s in Los Angeles at the height of the war between the corrupt L.A. police department led by Police Chief William Parker and Mickey Cohen's infamous mob that controlled Los Angeles' criminal underworld.

Jon Bernthal is said to be playing the other lead character, Joe Teague; a police officer who is caught up in the conflict between Parker and Cohen. Teague also served in the marines during World War II alongside Ventimiglia's Stax, giving the two characters a pre-existing connection.

Ventimiglia is best known for his role as Peter Petrelli through four seasons of NBC's "Heroes" as well as his three year run on "Gilmore Girls" and his turn as Rocky Balboa's son in "Rocky."

Darabont is set to write and direct the pilot and executive produce the potential series for "L.A. Noir." Michael De Luca and Elliot Webb are also attached to "L.A. Noir" as executive producers.
